Bursitis Of The Foot Anatomy

Overview
Retrocalcaneal bursitis is the inflammation of the retrocalcaneal bursa, which is located behind the heel bone, also known as the calcaneal bone (hence the name retrocalcaneal). The retrocalcaneal bursa is a thin, slippery, fluid-filled sac that serves as a both a cushion and lubricant between the heel bone and the Achilles tendon. Inflammation of the retrocalcaneal bursa usually results from irritation of the bursa. This irritation may be due to certain activities, an underlying health condition such as arthritis, or an abnormality of the foot, such the development of a boney prominence on the calcaneal bone, called a Haglund's deformity.

Causes
The swelling is the result of the blockage of blood, tissue fluids and circulation in the heel because their normal movement has been disrupted by the force of the injury. Just like cars back up behind a traffic jam, causing congestion, exhaust and overheating, blood and fluids back up behind the injured heel, causing pain, inflammation, lumps and swelling.

Symptoms
In retrocalcaneal bursitis, pain at the back of the heel is the main complaint from patients. Pain may worsen when tip-toeing, running uphill, jumping or hopping. Often, those who are accustomed to wearing high-heeled shoes on a long-term basis may also complain of pain at the back of the heel when switching to flat shoes. This is because when in high-heeled shoes, the calf muscle and the Achilles tendon are in a shortened position. Switching to flat shoes would cause an increased stretch to the calf muscle and Achilles tendon, irritating the Achilles tendon and the retrocalcaneal bursa. Other symptoms may include redness and swelling at the back of the heel.

Diagnosis
During the physical examination of a patient with calcaneal bursitis, the physician should keep the following considerations in mind. Swelling and redness of the posterior heel (the pump bump) may be clearly apparent. The inflamed area, which may be slightly warm to the touch, is generally tender to palpation. Careful examination can help the clinician to distinguish whether the inflammation is posterior to the Achilles tendon (within the subcutaneous calcaneal bursa) or anterior to the tendon (within the subtendinous calcaneal bursa). Differentiating Achilles tendinitis/tendinosis from bursitis may be impossible. At times, the 2 conditions co-exist. Isolated subtendinous calcaneal bursitis is characterized by tenderness that is best isolated by palpating just anterior to the medial and lateral edges of the distal Achilles tendon. Conversely, insertional Achilles tendinitis is notable for tenderness that is located slightly more distally, where the Achilles tendon inserts on the posterior calcaneus. A patient with plantar fasciitis has tenderness along the posterior aspect of the sole, but he/she should not have tenderness with palpation of the posterior heel or ankle. A patient with a complete avulsion or rupture of the Achilles tendon demonstrates a palpable defect in the tendon, weakness in plantarflexion, and a positive Thompson test on physical examination. During the Thompson test, the examiner squeezes the calf. The test is negative if this maneuver results in passive plantarflexion of the ankle, which would indicate that the Achilles tendon is at least partially intact.

Non Surgical Treatment
Specific treatment for bursitis will be determined by your doctor based on your age, overall health, and medical history. Extent of the condition. Your tolerance for specific medications, procedures, or therapies. Expectations for the course of the condition. Your opinion or preference. The treatment of any bursitis depends on whether or not it involves infection. Aseptic bursitis. A noninfectious condition caused by inflammation resulting from local soft-tissue trauma or strain injury. Treatment may include R.I.C.E. Rest, Ice, Compression, and Elevation. Anti-inflammatory and pain medications, such as ibuprofen or aspirin. Aspiration of the bursa fluid for evaluation in the laboratory. Injection of cortisone into the affected area. Rest. Splints.

Surgical Treatment
Surgery. Though rare, particularly challenging cases of retrocalcaneal bursitis might warrant a bursectomy, in which the troublesome bursa is removed from the back of the ankle. Surgery can be effective, but operating on this boney area can cause complications, such as trouble with skin healing at the incision site. In addition to removing the bursa, a doctor may use the surgery to treat another condition associated with the retrocalcaneal bursitis. For example, a surgeon may remove a sliver of bone from the back of the heel to alter foot mechanics and reduce future friction. Any bone spurs located where the Achilles attaches to the heel may also be removed. Regardless of the conservative treatment that is provided, it is important to wait until all pain and swelling around the back of the heel is gone before resuming activities. This may take several weeks. Once symptoms are gone, a patient may make a gradual return to his or her activity level before their bursitis symptoms began. Returning to activities that cause friction or stress on the bursa before it is healed will likely cause bursitis symptoms to flare up again.
